sharpened pin B is fixed in the bottom for insertion in the joist.

On the top of. the hanger is formed a hook or arm C for hanging it on awall or beam. In the bend of this hook or arm are made corrugations a ato give it greater strength. In the case the hanger is intended forattachment to a brick wall the hook or arm has an additional uprightbend a, by means of which it may be anchored in the wall. When thehanger is used on wooden beams, a pin 0 may be fixed on the under sideof hook C. In some instances the hangers that are to be used on woodenbeams may have ears d at each side.

As seen in Fig. 5, the hanger may be shortened and attached to a metalbeam. Holes may also be made in the sides of the hanger for securing thejoists in place with screws or nails.
